COKE-PUSHER.

SPECIFICATION forming part of Letters Patent No. 723,479, dated March 24, 1903.

Application filed June 5, 1902.

To all whom it may concern.-

' Be it known that I, EDWIN A. MOORE, a citizen of ,the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Coke-Pushers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates, primarily, to cokeovens of the type known as the Otto-Hoffman, has especial reference to means employed for discharging or pushing coke out of the ovens, and consists in certain improvements in construction whereby the pusherbar and its headare supported while being moved out from a car into and through an oven -and while theyare being withdrawn from an oven, as will be fully disclosed in the following specification and claims.

In theaccompanying drawings, which form .part of this specification, Figure 1 represents a side elevation of myimproved coke-pusher and a vertical section of part of an oven; Fig. 2, a side elevation showing the jib extended; Fig. 3, an end view showing the jib in its normal position; Fig. 4, aside elevation of the jib detached and part of the pusherbar in their normal positions andon an enlarged scale; Fig. 5,'a like view of a section of the 'pusher, showing the position of the movable carrier under the pusher-bar when the pusher-headhas been projected into an .oven; Fig. 6, a front end view of the. pusherhead, partly broken away to show the movable carrier; and Figs. 7, 8, and 9, respectively, vertical transverse sections of the pusher-bar on line 7 7, 8 8, and 9 9, Fig. 4..

Reference being had to the drawings and the numerals thereon, 1 indicates the car or truck propelled by a suitable motor 2, preferably an electrical motor, properly geared and connected to the axles of the car in any preferred manner.

3 indicates the pusher-bar,ha.ving a toothed rack& on its upper surface engaged by a pinion 5, driven bya train of gear-wheels 6, 7, 8, and 9, to which power is imparted by a suitable motor, (not shown,) and the bar is held down in engagement with 'revoluble bearings Serial to. 110,380. (No model.)

10 on the car-frame by a roller 11 engaging smooth tracks 12 on each side of the rack 4.

13 indicates a jibv or extensible section of the car-frame supported on a shaft 14, having bearings 15, is provided with inclined arms 16,-c0nnected near its upper end to the jib by bars 17, and limits the outward movement of the jib by the arm-16 engaging stops 18'on the main frame.

19 is a bracket secured to the upper end of the jib and supports revoluble carriers 20 20, secured to a shaft 21 and mounted in journal or shaft bearings 22, and the carriers are engaged by tracks 23 .on 'the lower surface of the pusher-bar. On the under side of the pusher-bar, adjacent to the head 24, are a recess 25 and a shoulder 26, the latterof which engages the shaft 21 as the pusher-bar starts outward to enter a coke-oven 27 and moves the jib 13and its carriers 20 outward until the arms 16 engage the stops 18, when the bar will pass over the carriers and the jib, and the carriers support the weight of the pusherhead 24 and the portion of the bar 3 beyond the frame of the car.

On the return stroke of the pusher-head in Withdrawing it from an oven the inner faces 28 of the head 24 of the pusher engage the carriers 20 and draw the extended jib back to its normal position.

The weight of the pusher -hea d 24 being supported on the jib 13 and its carriers 20,the bottoms of the coke-ovens are prevented being injured or destroyed by the head resting upon it as the pusher-head is projected through the ovens to discharge coke or while it is being withdrawn from the oven, thus increasing the durability of the ovens and greatly reducing the expense incident to repairing the bottoms of the ovens.

The pusher-bar 3 is composed of plates 29, of rolled plate-iron, having laterally-extending tracks or flanges 23 on its lower edge and tracks 12 at its upper edge, which are engaged. by the roller 11 and the parts secured togemer in the usual'manner of connecting structural iron.

Having thus fully described my invention, what I claim is 1. A coke-pusher having an extensible jib pivotally secured at its lowerend to the frame of a car, and provided with revoluble carpiVotally secured at its lower end to the frame riers; in combination with a. pusher-bar engaging said carriers. r

2. A coke-pusher having an extensible jib pivotaii'y secured at its lower end to the frame of a, car, and provided with revoluble' carriers; in combination with a. pusher-bar supported by said jib and carriers, and provided with means for projecting and retracting the jib.-

3. A coke-pusherhaving an extensible jib of a car, and provided with revoinble carriers; in combination with a, pusher-bar supported bysaid jib and carriers, and provided with a shoulder adjacent to the head for projectingthe jib.

In testimony whereof I afiix my signature in presence of two witnesses.
